Add non-mandatory JSON-LD profile

[nichtich]

To automatically map DAIA/JSON to RDF (if possible). Looks like JSON-LD 1.1 can help.

A start. Some parts will be tricky, e.g. part cannot be supported. Maybe this requires an extension to the holding ontology.

document can be mapped to dc:hasPart (or schema:hasPart) and organization to dc:creator (or schema:creator) when the result root is seen as bibo:Collection (or schema:Collection)

Another look at BIBFRAME 2 is worth to consider: https://www.loc.gov/bibframe/docs/pdf/bf2-items-apr2016.pdf The BIBFRAME ontology includes several properties also required in DAIA (bf:subLocation, bf:heldBy...)

The Holding-Ontology should switch to BIBFRAME 2. There are serveral aligments.
